Introduction to Electrical Impedance (Z-01)

Pencast PDF Notes here: https://drive.google.com/open?id=0B40... This is the first lesson in a series of lessons introducing the concept of electrical impedance as a way of solving electric circuits involving energy storage elements. In this first lesson the impedance for each of the resistor, capacitor, and inductor is derived by considering the ratio of voltage to current associated with each element when the excitation is of the form e^s*t. The impedance concept is then applied to a series RLC circuit to show that the previously found characteristic equation (associated with the circuit's corresponding differential equation) can be arrived at via circuit laws (KVL, KCL) and the impedance of each element, thus bypassing the need to write a differential equation. This is good news for those who prefer algebra over differential equations!
